History

  OHTO Co., Ltd. Tokyo, Japan was founded in 1929. 
It is one of the long-established pen manufacturing companies in Japan. 
In its long history, the company has made a number of advanced inventions and left its mark in the writing instrument industry of Japan and the world as well.
It was after the Pacific War that ballpoint pens began to be manufactured in Japan.
Ballpoint pen was first developed by Hungarian Laszlo Biro in 1943 and spread to the world, especially in the United States, after World War II.
In 1949, OHTO launched a pencil-shaped wooden ballpoint pen and became the first ballpoint pen manufacturer in Japan.

First ballpoint pen manufactured in Japan(OHTO), 1949

The ink of ballpoint pen is high viscosity oil-based ink. Thus writing was not so smooth. 
In 1964 OHTO surprised the world by developing a water-based ink ball point pen.
These days, it is called Rollerball Pen

World's first water-based ink ballpoint pen pioneered by OHTO in 1964

Now a days, so many manufacturers are making Roller pens which was first innovated by OHTO. 
OHTO's water-based ink refill(C-300 Ceramic Roller Refill) is still the standard refill for Roller Pens in Japan.
Many global manufacturers are using Ceramic Roller Refill in their high quality Roller Pens.

In 1999, OHTO developed a new concept "NEEDLE-POINT" in ballpoint.
It is a combination of oil-based Soft ink and Needle shaped tip.
In this ballpoint pen, the Tip is changed from conventionl Cone shape to pipe like Needle shape. 
It secures a wide field of view at the time of writing, making it easy to see the pen point, convenient to draw a line with a ruler.
NEEDLE-POINT became the synonymous with OHTO.

Now, OHTO produce NEEDLE-POINT Roller pen, Ball pen(soft ink) and Gel pen as well.

With Japan's first mass-produced ballpoint pen, the world's first water-based ballpoint pen, the world's first gripper pen, and NEEDLE-POINT, it turns out that OHTO is a manufacturing company with an innovativeness and originality that makes it different from others.
